People will apply this to something like gay pride, black pride, etc. But those forms of pride are about standing in opposition to prejudice, oppression, and hardship, where the inherent aspects of your existence are demonized, stereotyped, or seen as lesser. The pride is in making it through the world and accepting/celebrating yourself despite all the hate and dangers others force onto you.

Having pride in being part of a marginalized group isnt about feeling superior to other groups. It is about rebelling against those who feel themselves superior to you.
